At present, a common C-type usb adapter board in the market is composed of a C-type usb female connector, a signal adapter circuit board, and a pin end, where the C-type usb female connector is electrically connected to a plurality of pins of the pin end through the signal adapter circuit board. The C-type universal serial bus female connector is connected with a corresponding cable access signal, and a contact pin end leads out a signal required by a user through a DuPont wire, so that the C-type universal serial bus female connector is very convenient to use compared with the C-type universal serial bus female connector with dense pins for leading out the signal required by the user directly. However, in practical production and application, when the C-type usb adapter board is connected to the cable each time, the pins at the pin end need to be checked for signal definition (i.e. what kind of signal the signal led out by each pin is determined first), which affects efficiency very much, and the connection between the dupont line and the pins is very easy to loose, which is likely to cause poor contact, and may cause great inconvenience in application.
In summary, it can be seen that there has been a long-felt need in the prior art for a conventional C-type usb adapter board to check whether the signal definition of each pin is correct during each connection with a cable, and a problem that the connection is easily loosened due to the connection between the dupont line and the pin.
